Abstract

MgAg_0.97Sb_0.99 was found to be potentially a new class of thermoelectric materials with ZT values above 1 in the temperature from 100 to 300°C. In this report, we systematically studied the effect of Na doping in Mg, Mg_1-xNa_xAg_0.97Sb_0.99, on the thermoelectric properties and found Na was effective to increase the carrier concentration and power factor, especially below 180°C, which led to higher ZT values, a better self-compatibility factor, and ultimately a higher output power at the optimal Na concentration of x=0.005-0.0075.
